Question about home button.. Please check!

Ever since I got my Active, my home button just doesn't click or have as much resistance as the other 2. It also sometimes feels loose. Hard to explain. A coworker of mine has the Active and his feels better.
But now today I noticed that the 2 silver accents on the side of the home button press down or move when I press the home button. It's probably attached to the home button, but never noticed this before. Can you guys check and see if this happens to you and if this is normal? Everything works ok. I'm just anal. I feel like my home button will wear out. Thanks guys!
